Dylan Dougherty received the maximum prison sentence Monday for his guilty plea to one charge of first-degree assault. His brother and sister are also to be sentenced Monday.

All three siblings are accused of shooting at a police officer and staging a bank robbery before being captured in Colorado following a car chase and shootout with police last August.

After sentencing, they're expected to be transferred from state to federal custody within days, if not hours. The U.S. Marshals Service will transport them to Albany, Ga., for a court hearing on May 15.

The widely publicized cross-country manhunt for the Doughertys ended Aug. 10 in Huerfano, Colo., after a pursuit on Interstate 25.

The Doughertys allegedly fired an AK-47 at pursuing officers before running over spike strips, blowing a tire, rolling their vehicle and crashing into a guardrail.

The trio made off with about $5,200 and had spent about $1,000 of it by the time police caught up with them in Colorado, authorities said.

Ryan Dougherty told authorities in Colorado that the trio hoped to escape to Mexico. The siblings told investigators they traveled across the country in a stolen car, taking back roads to avoid detection.
